IMPROVEMENT IN SASH-FASTENER S.

Specification forming part of Letters Patent No. 208,124, datedSeptember 17, 1878 application filed January 24, 1878.

To all whom it may concern:

Be it known that I, SYLvEsrER Itoor, of Kentland, in the county ofNewton and State of Indiana, have invented certain new and usefulImprovements in Sash Supporters and I Fasteners; and I do hereby declarethe followin g to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawings, which form part of this specification. v

My invention relates to improvements in sash supporters and fasteners;and consists in the novel combination, with a corrugated locking-stripsecured within a vertical recess of the sash, of a spring-pressedbolt-provided with a serrated locking-face and made as hereinafter morefully described and claimed.

I11 the drawings, Figure 1 is a view of a sash and sash-frame in brokensection provided with the invention. I i g. 2 is a side or edge view ofa sash, and Fig. 3 is a detail View of the peculiar lockingbolt.

The side or stile A of a sash is formed with a vertical central recess,in which the corrugated locking-strip B is suitably secured. This stripI preferably make of flexible sheet metal, so that it can be readilybent or crimped into the corrugated form shown.

The locking-bolt G is made with a serrated or notched working-face,adapted to engage with two or more of said corrugations. It is securedin a transverse recess made in the conti guous jambD of the sash-frame,and is formed spring-pressed as follows: The plate E has the bolts D andthe thumb-piece F formed rigidly therewith, and both the latter passthrough their respective workin g-slots in the faceplate G. v The spiralspring H is inclosed within the sleeve h formed on the thumb-piece, andby reason of its inner end bearing against the face-plate and its outerend bearing against the head of the thumb-piece the latter is forcedoutward. Since the face-plate is secured within the recess of the jamb,so as to be stationary therein, while the inner plate is left free forreciprocating horizontal movement, it follows that the movement of thethumb-piece F carries with it the inner plate, E, and the bolt D.

I am aware that it is old to use the combination, with a corrugatedlocking strip, of a serrated-faced bolt which engages therewith, andhence I do not claim the same; but my invention consists in theimprovement set forth in. the claim.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination, with a corrugated lockingstrip secured within avertical central recess in the sash, of a sash-fastener, which consistsof bolt D, having a serrated working-face, inner plate, E, thumb-pieceF, and fixed slotted plate G, said thumb-piece provided with spiralspring H and inclosin g-sleeve h, all constructed and adapted to operatesubstantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this19th day of January, 1878.
